hereby declare under our own and sole responsibility that the product: MODERATOR
central-heating boiler, with serial numbers starting from 400, to which this declaration
applies, meets the following requirements and standards, as applicable:
Directives Standards
97/23/WE EN-PN- 303-5
Hajnówka, 2004.02.01
1.3. Fuel
Use only fuels recommended by the manufacturer.
The Moderator boiler is designed to burn renewable fuels, wood-based
and vegetable-based fuels(pieced wood, chips, sawdust, bark) with moisture
content of up to 30%. Coal may be used as a substitute fuel.
Technical parameters of the boiler are specified for fuels with humidity
content of up to 30% and with calorific value of Q=17.084 kJ/kg for wood and
of Q=29.924 kJ/kg for coal.
The higher the moisture content, the lower the calorific value (note: an
increase of moisture content causes calorific value to drop, which means that
one will need twice as much fuel to achieve the same heating effect). A
considerable part of thermal energy is wasted in the burning process for heating
up the fuel and evaporating water (note: using wet fuel directly contributes to
shortening of boiler’s operational life and causes it to wear out prematurely).
Hygrometers are used for moisture content measurements (different types are
used for sawdust and different for wood). These are necessary equipment, which
should be used when purchasing fuel (to check the actual moisture content) as
well as during normal operation of the boiler.
